FIT TIP #1 — JUNE 2021

Corrosion Kills Rubber,
Not Polyurethane.

ATRO FIT stage 1.
PROBLEM

Worn or failed torque rods with rubber bushings.

See  VISUAL CLUES FOR BAD TORQUE RODS below.

ATRO FIT stage 2.
ROOT CAUSE

Corrosion from oil, grease, cleaning solvents, rock salt, hydraulic fluids, diesel fuels, and other chemicals often cause elastomer and rubber bushings to deteriorate and fail.

See  YOUTUBE VIDEOS below.

ATRO FIT stage 3.
COSTS

• Increased maintenance costs.
• Wear on suspension, tires, steering, and other components.
• Safety issues and risk of costly CSA points violations.

See  WHY IS THIS IMPORTANT? below.

ATRO FIT stage 4.
CORRECTIVE ACTION

1. Inspection
2. Replace worn torque rods or torque rod bushings with new ATRO polyurethane torque rods with free-rotation bushings. The ATRO bushing “freely” rotates 360 degrees and is designed to fit all clocking angles.

See  INSPECTION SCHEDULES below.

ATRO FIT stage 5.
EXPECTED OUTCOME

With ATRO polyurethane torque rods and bushings, you can expect to save time and money because installation is faster and simpler, and our parts last 3-5 times longer than rubber.
Your trucks will spend less time in the shop, and more time on the road.

See  THE ATRO SOLUTION below.

  WHY IS THIS IMPORTANT?

The torque rods on your trucks maintain proper suspension alignment. Worn torque rods cause these problems:

  • Excessive tire wear—A bad tire caused by a bad suspension part can lead to long list of problems, not the least of which is points and CSA violations.
  • More fuel consumption—The truck is working harder to overcome resistance from bad suspension parts.
  • Wear and deterioration of other critical driveline and suspension components.

 Get more info at the Torque Rod page.

  INSPECTION SCHEDULES

Inspect your torque rods on a regular basis. Look for signs of wear, and replace worn torque rods.

Regular inspection for torque rod failure is critical to the safety and performance of your fleet. The recommended inspection schedule is:

  • OTR Trucks—every 50,000 miles or 6 months
  • Heavy-duty vocational applications—every 90 days
  • Trailers that run empty—every 90 days
    (bouncing can cause early failure)

 See Inspection Methods below.

  THE ATRO SOLUTION

Replace worn torque rods or torque rod bushings with new ATRO polyurethane torque rods with free-rotation bushings.

The ATRO bushing “freely” rotates 360 degrees and is designed to fit all clocking angles. This results in a smoother ride—especially on rough or uneven surfaces—and reduces stress on other key systems and components of the truck.

INSPECTION METHODS

 VISUAL CLUES
FOR BAD TORQUE RODS

ATRO visual clues for torque rod inspection: corrosion.
CORROSION

Caused by failed paint or powder coating, or exposure to caustic chemicals such as acid wash, or road salt. Visual clue: look for corrosion on the exterior surfaces of the rod. This is a safety hazard and the rod should be replaced.

ATRO visual clues for torque rod inspection: bushing windup
BUSHING WINDUP

Caused by improper bushing angle, bushing and ride height not “at zero” or equal angles. The result is accelerated wear of the bushing due to pre-loaded rotational force. Visual clue: look for radial cracks in the rubber bushing around the pin.

ATRO visual clues for torque rod inspection: bushing walkout.
BUSHING WALKOUT

Caused by misalignment, or installation lubricant not allowed to dissipate, or a bond failure. Visual clue: excessive rubber exposed on one side and often metal-on-metal on the opposite side.

ATRO visual clues for torque rod inspection: bushing extrusion or deformation.
BUSHING EXTRUSION OR DEFORMATION

Also called deformation. Caused by exceeding the rating of the bushing and overloading the suspension, or “oil soaked” when rubber is in prolonged contact with chemicals such as oils, engine fuels, hydraulic fluids, cleaning agents. Visual clue: the rubber becomes soft and pliable and the weight of the truck extrudes it out of the sides of the bushing.

ATRO visual clues for torque rod inspection: dry rot.
DRY ROT

Caused by age, heat, UV rays, temperature extremes, ozone, oxidation, and lack of use. It is evident by cracks in what otherwise appears to be a good bushing. This is a sign that the material has been compromised and should be replaced.

ATRO visual clues for torque rod inspection: catastrophic failure.
CATASTROPHIC FAILURE

Almost always caused by poor preventive maintenance and is almost always the result of some other system or component problem going unchecked. Visual clue: torque rod and bushing are destroyed.

ATRO visual clues for torque rod inspection: damaged grease seals.
DAMAGED GREASE SEALS

Caused by age and contact with foreign objects. Once the seal is broken, the lube leaks causing metal-on-metal. Visual clue: rubber or ball-type bushing deformed and exposing metal-on-metal at the bushing joint.

ATRO visual clues for torque rod inspection: bent or broken torque rods.
BENT OR BROKEN TORQUE RODS

Bent caused by hard impact, or improper rod length. Broken are rare, but typically caused by exceeding the load rating of the suspension. Broken transverse rods can be caused by misalignment.

ATRO visual clues for torque rod inspection: damage to straddle or taper pins.
DAMAGE TO STRADDLE/TAPER PINS

Caused by impact, or severe misalignment, or out-of-round brackets due to improper bushing removal.

ATRO visual clues for torque rod inspection: worn mounting hole.
WORN MOUNTING HOLE

Caused by loose or over-tightened fasteners.
